Question

GIven: AB is a tangent of point X. AB=70 and XD=12. What is the measure of DB

Answer 1

Diagram

Answer 2

u mean the length of DB ?

Answer 3

Yes, what is the length of DB

Answer 4

if yes, use the pythagorean theorem :
DB^2 = AD^2 + AB^2
with AD = 2DX

Answer 5

So the answer would be 74, correct?

Answer 6

yes, i got like that too

Answer 7

Okay can you help me with one more?

Answer 8

Given: DC is a tangent of E. AE = 20 and DC = 9 what is the length of AC?

Answer 9

do same idea like 1st,
AC^2 = AD^2 + CD^2 (with AD = 2AE)

Answer 10

So 41?

Thanks!!

Answer 11

yep, that's right
